1 Production Process Optimization2 Production Equipment Optimization3 Slurry Recovery Process4 Quality Control Measures2.3.1.1 Optimization of Dry Production ProcessGood gradation, appropriate fines content, low mud content, and a reasonable grain shape are the characteristics of high-quality MS. The waste tailings stone particles with 3–5 mm size produced in the processing of high-quality stones are used as raw materials for the production o2.3.1.2 Optimization of Wet Production ProcessThe disadvantage of the wet production process is that the fines content of produced sand is low, which has negative influence on the quality of MS and the performance of concrete mixture, as well as the environment. However, the fines content and the wastewater could be controlled wit在link.springer上Email: jzhw@tongji
